^ 3 Claims.

This invention relates to certain'new and useful improvements in spraying attachment for tractors. t

The primary object of the -invention is to provide a spraying attachment for tractors of standparts of the spraying attachment from the trac-l tor frame. Y

A further object of the invention is to provide a spraying attachment for tractors of standconstruction wherein the spraying attachforwardly of and rear ground wheels of the tractor with means to facilitate discharge of the spraying solution rearwardly of the tractor, the

easily maneuvered.

With the-above and other will become apparent as the tion is better understood, the same consists in the novel of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings:-

Figure 1 is a top plan view of afspraying atrelation to the tractor;

Figure 2 is a side elevational View, partly Figure 3 is a diagrammatic view showing -the spray solution tanks and the driving connections from the tractor motor to the sprayingl pump and tank agitators; and

Figure 4 is a detail cross-sectional View taken on line 4 4 of Figure 2. l A

The standard tractor illustrated comprises the rear drive wheels I 0 supported by axles within the rear axle housing II, frame bars I2 extending forwardly of the rear axle housing II for the support of forwardly positioned steering Wheels I3 controlled in their operation by thel steering devices I4. A

in general by the reference character I5 is suphousing I1 associated with the rear axle housing II as shown in Figure 1. v

The spraying attachment for the tractor is at- As shown in Figure 4, each bolster 20 has a A curved seat 23 adjacent each end thereof for the support of a pair 2l communicate with each other through the i medium of a tube Il extending between the rear ends of the tanks and entering the tanks at the bottoms thereof as shown at ll in Figure 4.

A platform bar 35 extends transversely of the side bars I8 rearwardly of the axle housing Il and is anchored at its ends as at I5 to said side bars, a pump 31 being mounted upon the platform bar 35 and having an outlet pipe I8 communicating with a manifold pipe 39v disposed above an end transversely extending bar I0 carried by the rear terminal ends of the side bars I8, spray pipes Il carrying nozzles 42 being-carried by the manifold pipe 39 for discharging and spraying the insecticide or other spraying fluid rearwardly of vthe tractor. A pipe Il extending from the pump 31 has braifch connections 44 with the tanks 2l and 25, the pump drawing the lprovided in each of spray solution from the tanks for discharge through the spray nozzles I2.

Mixers or agitators for the spraying fluid are the tanks 2l and 25 and power for the operation of the agitators and pump 31 is derived from the motor drive l5. A power shaft 45 is driven from the motor of the tractor, the driving devices being mechanically illustrated in Figures 1 and 2 and diagrammatically illustrated in Figure 3, the drive shaft l5 having a sprocket wheel thereon communicating rotary motion to the pump shaft 45 through the medium of a sprocket chain 41. A second sprocket wheel on the pump shaft 41 communicates motion to the counter-shaft I8 through the medium of the sprocket chain Q and a second sprocket Wheel on the counter-shaft 48 communicates rotary motion to the agitator shaft 50 in the tank 25 chain 5I. The agitator shaft 52 in the tank 2l has a sprocket wheel that is driven by a sprocket chain 53 that also passes over a second sprocket `1 wheel on the agitator shaft 50 in the tank 25.

From the above detailed description of the invention, it is believed that the construction and use thereof will`| at once be apparent, it being noted that the spraying attachment Aincluding its base frame is readily attachable to a tractor of standard construction, the tanks for the spraying solution being arranged in a pair with a. tank respectively positioned at each side of the drive I5 and forwardly of the rear ground A wheels I0, with the spraying mechanism well balanced upon the tractor frame, and while there i is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

the rearwardly extending frame through the medium of the sprocket I claimzl. A spraying apparatus adapted to be attached to a tractor, wherein the tractor 4embodies rear traction wheelsand a .forward power plant. a frame structure adaptedgto be secured -to the tractor in overlying relation thereto,` two communicating tanks carried by the frame structure respectively at opposite sides of the power plant of the tractor and forwardly of the traction wheels, vthe frame structure extending rearwardly of the traction wheels a pump supported on portion, means forming communication between the pump and tanks, spray devices rearwardly of the pump and in communication therewith and operative connections between the pump and power plant.

2. A spraying apparatus adapted to be attached to a tractor, wherein the tractor embodies rear traction wheels and-a forward power plant, aframe structure adapted to be secured to the tractor in overlying relation thereto, two communicating tanks carried by the frame structure power plant includingl a drive shaft extending from the power plant Jand a drive connection between the power shaft and pump.

3. A spraying apparatus adapted to be attach-I ed to a tractor, wherein the tractor embodies t rear traction wheels and a forward power plant, a frame structure adapted to be secured to the tractor in overlying-relation thereto, two communicating tanks carried by .the rframe structure respectively at opposite sides of the power A plant of the tractor and forwardly of the traction wheels, the frame structure extending rearwardly of the traction wheels, a. pump supported on the rearwardly extending frame portion,

means forming communication' between the pump and tanks, spray devices rearwardly of the pump and in communication therewith and operative connections between the pump and power plant,the operative connections between the pump and power plant including a drive shaft extending from the power plant and a drive connection between the power shaft and pump, an agitator in each tank, drive connections between the agitators and drive connections between the pump shaft and one of the `agitators.
